Title:
Ubuntu 18.04 No audio from speakers. Headphones working. Surface Pro 3
Status in alsa-driver package in Ubuntu:
Confirmed
Bug description:
I updated my Surface Pro 3 From Ubuntu 17.10 to Ubuntu 18.04 (did a clean
install) and the only audio working was from the headphone jack.
I tried all these:

[this
answer](https://askubuntu.com/questions/117842/no-sound-from-speakers-but-headphones-work)
[another
answer](https://askubuntu.com/questions/829520/ubuntu-16-04-no-sound-from-speakers-only-headphones-working)
I went back and tested the live CD and even the live cd has no audio
through the speakers. so this must be related to 18.04. I never had
sound issues before and under windows audio still works correctly.
here is my alsa iformation http://www.alsa-
project.org/db/?f=8bf135db52610a603014779ef24041a491c8a32d
and here is how I fixed it:
renaming /etc/modprobe.d/alsa-base.conf to /etc/modprobe.d/alsa-
base.bk , then rebooting the computer fixed the my speaker sound
issue.
I then restored line by line in to /etc/modprobe.d/alsa-base.conf, rebooting
between restored lines, until all lines were back.... and ... it still worked!
so I restored the original /etc/modprobe.d/alsa-base.conf and rebooted the
computer and everything was still working....
so I am not sure what the problem was but is now fixed.
